SIDNEY l3. IVHITESIDE, OF LOS. ANGELES, CALIFORNIA.

STAMP-CANCELING AND DATING MACHINE.

SPECIFICATION forming part of Letters Patent No. 440,675, dated November 18, 1890. Application filed February 15, 1889- Serial No. 29.9;987. (No model.)

To all whom it may concern.-

Be it known that I, SIDNEY B. WHITEsIDE, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Improvement in Stamp-Canceling and Dating Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

Figure 1 of the drawings represents a side elevation slightly in perspective, of my improved machine. Fig. 2 is a perspective view showing the opposite side of the machine with part of the frame and gearing omitted. Fig. 3 is a fragmentary cross-section illustrating the means for securing the self-adj usting table when it is desired to hold the same stationary.

The object of my invention is to provide a stamp-canceling and dating machine which can be operated by foot-power or other suitable power, relieving the operator of much labor and leaving both his hands free to manipulate the letters operated upon.

My invention comprises the combination of a pivoted vibrating arm, means for vibrating the arm, a reversible stamp provided with 1aterally-projecting reversing-lugs and pivotally secured to the free end of such arm by an axle located between the reversing-lugs and the face of the stamp, a stamping-table, and a frame provided with an inking-pad and with a cam-guide groove arranged between such table and pad, approximately in the arc described by the stamp when'the arm is vibrated.

It also comprises the combination, with such mechanism, of a self-adj Listing table, whereby the letters of a pack can be conveniently operated upon successively.

The drawings illustrate a machine embodying my invention.

The driving-band wheels A A and crank a, connected to the latter for operating pitman b and bent pivoted vibrating arm B, are mounted upon frame 0, as shown in Fig. 1. The bent vibrating arm 13 is pivoted to the rear of the frame of the table, and its short arm B projects rearwardly for connection with pitman b.

The bifurcated end of the arm B carries the pivoted socket cl, in which the removable stamp e is secured bya set-screw. The socket d is secured on the short axle-pin f, journaled in the branches 1 2 of the bifurcated end of arm 13, the opening between said branches being of sufficient capacity to permit the socket (Z and the stamp connected therewith to pass between them when being reciprocated and reversed in position, as hereinafter specified. The end of socket d is rigidly fixed to the guiding pivot-rod g, which extends at each end through cam-slots J, formed in the curved portions of frame 0 O, which cause a reversion of the stamp as it passes the short curve '0 in said slots.

The self-adj usting table D, upon which letters or other articles to be stamped or can celed are placed, is fitted in the frame of the machine and supported by spiral springs h, which serve to cushion the action or percussive effect of the stamp as it strikes the article placed under it to receive its impression.

The ink-pad t is centrally vpivoted to the frame in proper position to be struck by the stamp below its center as it is caused to revolve slowly by the action of the pawl 7r, pivoted at its lower end near the elbow of arm B, said pawl working in the ratchet-wheel con nected to the back of the centrally-pivoted ink-pad.

The arms m a, connected by pins to the whiftlebar o, pivoted underneath to table D, work in holes formed in the table-frame at p to hold the outer end of the table when the thinner papers or letters are to be stamped or canceled, and the ends of said arms m a, when adjusted in said holes, will rest on rubber blocks Q to cushion the table, and thus prevent noise when the stamp strikes it or a letter resting upon it. \Vhen the arms mnare withdrawn, by turning the Whifliebar 0 on its pivot the table will rest upon the spiral springs h h, which will permit the table to descend to a greater distance when packages or papers of greater thickness than ordinary letters are being stamped.

To operate my machine, the attendant will actuate the band-wheels A A by the treadle T, which will in turn move the pitman 19, connected with short arm B of arm 13, causing movements in either direction, the short curve 22 being out of the true are of the circle, the socket and stamp attached thereto Will be reversed in position thereby, so as to bring the face of the stamp against the table and against the ink-pad alternately. As the attendant operates the machine by the treadle, he Will be free to manipulate the letters orother matter being stamped or canceled upon the table, placing them in position to receive the stamp and adjust them in the box for removal.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a stamp canceling machine, the combination of the table, the frame provided with the cam-shaped guiding-slots and the inkingpad, the bent vibrating arm pivoted to the frame, means for vibrating the arm, and the reversible canceler pivoted to such vibrating arm and provided with the guiding pivot-rod.

2. In a stamp-canceling machine, the combination of the self-adjusting table, the pivoted vibrating elbow-arm, the reversible canceler pivoted thereto and provided with the guiding pivot-rod, the frame provided with the cam-shaped guiding-slots, and the inking-pad.
